作業員の位置測定システム

Japanese Patent JP7338815

B2

Provided is a worker position measurement system that is unlikely to reduce the work efficiency of work in a building equipped with an elevator. A position measurement system (21) comprises a measurement unit (28), an estimation unit (30), a correction unit (31), and a calculation unit (32). The measurement unit (28) measures the height-direction position of a worker on the basis of a reference atmospheric pressure at the position of a reference atmospheric pressure measurement unit (22) and an atmospheric pressure of interest measured at the position of the worker. The estimation unit (30) estimates the height-direction position of the worker when an elevator (1) event is detected. The correction unit (31) converts the reference atmospheric pressure or atmospheric pressure of interest so as to correct an estimated altitude difference between the reference atmospheric pressure measurement unit (22) and the worker for the time when the height-direction position of the worker was estimated. The calculation unit (32) uses the difference between reference atmospheric pressure and atmospheric pressure of interest after the conversion by the correction unit (31) to calculate an offset value to be used by the measurement unit (28) to correct the reference atmospheric pressure or atmospheric pressure of interest.
